Abstract (en)
[origin: EP4024534A1] Provided is a binder composition for an electrical storage device, which enables the production of an electrical storage device electrode being excellent in flexibility and adhesiveness, and showing a satisfactory charge-discharge durability characteristic. The binder composition for an electrical storage device according to the invention includes: a polymer (A); and a liquid medium (B), wherein, with respect to 100 parts by mass in total of repeating units contained in the polymer (A), the polymer (A) contains: 20 parts by mass to 60 parts by mass of a repeating unit (a1) derived from a conjugated diene compound; 35 parts by mass to 75 parts by mass of a repeating unit (a2) derived from an aromatic vinyl compound; and 1 part by mass to 10 parts by mass of a repeating unit (a3) derived from an unsaturated carboxylic acid, and wherein a THF-soluble component of the polymer (A) has a weight average molecular weight of from 100,000 to 600,000.
